The Oracle Hardware Management Pack packages can be uninstalled using native package tools, such as RPM, or using the wizard-based uninstaller that comes with the Oracle Hardware Management Pack. When the native package method is used to remove packages, the encrypted file that stores the cached user name and password for using over the LAN interconnected will not be deleted. This must be manually deleted.
The wizard-based uninstaller removes the credentials file. Therefore, Oracle recommends that the wizard-based installer be used to uninstall Oracle Hardware Management Pack.
